Caseous Rhinitis. — During- the last year or two Prof. 

 (lUarnaccia (Archivii Italiani di Laring-olog-ia, No. 4, 1896) 

 has made bacteriolog'ical researches upon caseous rhinitis. 

 These studies refer to a case observed by Massei in his 

 clinic. Guarnaccia has demonstrated that the micro- 

 organism found in rhinitis caseosa, which was so differ- 

 ently understood by Perier, Sabrazes, etc., is streptothrix 

 alba, or Foersterii, studied by Rossi-Doria, Cohn, and 

 Gasperini. The author was able to cultivate it in ag-ar 

 gfelatin, bouillon, blood-serum, potatoes, and milk. Inocu- 

 lations in animals were not successful. It is perfectly 

 correct, in his opinion, to assume that the considerable 

 amount of caseous matter is formed by the g-rowth of the 

 strei)tothrix, as is the case in mug-uet. — Universal Medi-

Tuberculosis in Goats. — From the following- it will be 

 seen that the hitherto accepted theory that g-oats are 

 immune to tuberculosis is not altog-ether correct. Bulling- 

 (Indian Medical Record) records a case of pulmonary 

 tuberculosis in a g-oat. Both lung-s were adherent, and 

 larg-e and small tuberculous foci were present. The 

 author concludes that it would be well to examine into the 

 possibility of the transmission of tuberculosis throug-h the 

 ag-ency of g-oats, and to consume their milk only after boil- 

 ing-, or after the g-oat has been shown to be free from 

 tuberculosis by the absence of reaction after the injection 

 of tuberculin.

Circulation of Blood. — Most books recommend the use 

 of a frog-"s fool, for this i)urpose and give directions lor 

 accomplishing the purpose. The object may easily be 

 attained with a small tadpole. Hazard, and with manv of 

 the larger water larvae. The latter will show the circu- 

 lation all through the body. With the lizzard and tadpole, 

 it may best be seen in the thin membranes of their tails. 

 All that is necessary is to place the animal in a glass slip 

 with a shallow cell and cover it.
